Numbers 9:2-7

LITV(i) 2 Also the sons of Israel shall prepare the Passover in its appointed season. 3 In the fourteenth day of this month, between the evenings, you shall prepare it according to all its statutes, and according to all its ordinances. 4 And Moses spoke to the sons of Israel to prepare the Passover. 5 And they prepared the Passover in the first month on the fourteenth day of the month, between the evenings, in the wilderness of Sinai, according to all that Jehovah had commanded Moses, so the sons of Israel did. 6 And there were men who had been defiled by the body of a man, and they had not been able to prepare the Passover on that day. And they came near before Moses, and before Aaron on that day. 7 And those men said to him, We are defiled by the body of a man. Why are we restrained so as not to be able to offer the offering of Jehovah in its appointed season, in the midst of the sons of Israel?
